dmaengine: Add Broadcom SBA RAID driver
The Broadcom stream buffer accelerator (SBA) provides offloading capabilities for RAID operations. This SBA offload engine is accessible via Broadcom SoC specific ring manager. This patch adds Broadcom SBA RAID driver which provides one DMA device with RAID capabilities using one or more Broadcom SoC specific ring manager channels. The SBA RAID driver in its current shape implements memcpy, xor, and pq operations.
